Lost Connections

I'm in the middle of the second outage I've seen in the past 8 hours. The errors coming in are:
ERROR MESSAGE:
ThinkingSphinx::SphinxError: Lost connection to MySQL server at 'reading authorization packet', system error: 0 - SELECT * FROM `matter_core`, `matter_delta` WHERE `user_id` = 686517 AND `sphinx_deleted` = 0 ORDER BY `updated_at` DESC LIMIT 0, 20; SHOW META

I'm able to `rake fs:index` but that doesn't resolve the issues. Your status page is reporting that our server, rusina, has no issues.

I haven't been able to get a successful query through since opening the ticket, but it appears to be intermittent. Looks like the first error was ~1.5hrs ago but the error count doesn't _look_ high enough that it's failing on every request.

Just further to this: the Sphinx proxy is now working again on
what was the primary server (which is now the new failover).
Considering this issue resolved, but if you see a return of it, do
let me know!
